The Audison SR 4.500 4-channel amplifier with crossover features great power packed into ultra-compact dimensions (130 W x 4 @ 4Ω).As far as the electronic design is concerned, every aesthetic and functional detail of the Audison SR 4.500 has been taken care of, resulting in a compact amplifier made of extruded aluminum with rounded corners, which facilitates the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, there is no need for internal cooling fans, which often cause noise and dust accumulation. In keeping with tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any kind of audio system configuration. The controls, protected by a satin-finished aluminium panel, are located on the top panel of the amplifier, so that they can be easily reached from above, even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.
